IRA W. IRAY AND EDWARD FITZHENRY, OF PORTLAND, OREGON. Letters Patent No. 61,250, dated January 15, 1867.

IMPROVED. MACHINE FOR SGOURING LEATHER.

y TO ALL WHOM IT MAY CONCERN:

Be it known that we; IRA W. PRAY, and EDWARD Frrzunnnr, of Portland, in the count State of Oregon, have invented a new and useful improvement in Machines for Finishing hereby declare that the following is a full, clearkand exact description of the same, annexed drawings, made part of this specication, in which- Figure 1 is a perspective view.

Figure 2 is partly a side elevation and partly a vertical section.

Figure 3 is an elevation of the opposite sides.

In the different gures the same letters refer to identical parts.

My improvements relate to the arrangement of a machine for finishing, means of' the usual steel, stone, or glass scouring tools attached to a frame i1 cating action of a crank and pitman the two ends shall .be brought alternately .into action.

A is a frame or plate, pivoted at its centre to the arms of the cross-head B, which is arranged to slide freely upon the Ways C, which arc suspended by the hangers D.' The frame A receives a reciprocating motion from the pitman N, which is attached toit and tothe crank N. The revolution of the crank gives an oscillating motion to each end of the yframe A aswell as a'reciprocating motion to the' entire apparatus. A series of Curved arms, H, are attached by a hinged joint to the cross-head B in such manner that they may have a vertical oscil- `lation; and to the ends of these arms another series of' similar arms, I, are in like manner hinged. These arms are intended to have an independent vertical play so as to adapt themselves to inequalities in the surface of the leather. On the under side of the arms H and I are jaws marked H/and I', respectively, fitted to receive the. square plates of steel, stone, and glass, L, ordinarilyA employed in cleaning and finishing leather; these plates L, adjustably held by the set-screws L passing through the arms above the jaws. Tb the outer extremities o t' the arms I are attached brushes M. The plates L are kept in contact with the leather by the stress of thesprings K, which, resting upon the arms, are attached to the cross-pieces K', which are so suspended upon journals fixed in the frame A that they may be turned by the levers O, which e series of arms he may desire, or increase the pressure as may be necessary. The side of the leather to be finished is attached tothe table G, and is kept in place by the roller E, which is suspended by the rods E from the bar P over the cross-head B. This bar P is attached to a lever, F, by which the height of the Toner E is regulated; and it is retained in the requiredposition by the notched catch F.

The operation of the machine is suiiciently indicated by the abc composed. The power is derived from any source capable of applic reciprocating motion is given to the entire apparatus, and at the sam frame A brings alternately the scrapers or slickers L into .contact their independent arrangement permitting them to a surface. l

Having fully explained t'he'construction and operation of my improved machine, tion, and seek to secure by Letters Patent, is-

1. A mechanism by which dually arranged sets of rubbers or sera may alternately be brought into action by the reciprocating motio setforth.

2. In .combination with the, crank N and pitman N we claim the frame A manner and for the purpose set forth. f

3. The combination of the hinged arms H, with or Wit out the arms I, with the springs K, the parts being constructed` and arranged for use substantially as set forth.

4. The springs K, pivoted cross-pieces K', and lever-s O, in combination with the hinged arms H and I, substantially as and for the purpose set forth;

5. In combination with the table G we claim the roller E, adjustably suspended by the rods E bar P, substantially as and for the purpose set forth.

y of Multnomah, and e Leather; and Wedo reference being had to the scouring, and glossing leather by i such manner that by the reciprove description of the parts of which it is ation bythe revolution of the crank. A e time an oscillating motion given to the with the face of the hide upon the table, ccommodate themselves to any ordinary irregularities of what I claim as my invenpers L, in a machine for finishing leather, n of a crank, substantially in the manner pivoted substantially in the and crossvIRA W.
